Way back uip the thread someone replied to me:

I wrote <<"And what if a black person wrote one, with the intention of performing it to a predominantly black audience? >>

To which the reply was <>

I was aware as I wrote it that such a thing happens, and that the debate on the rights and wrongs is very much alive in a certain section of some black communities, and amongst the chattering classes. However, I didn't want to open up that debate (thankfully, knowing little about rap music) but to put it forward as a hypothetical situation in a folk context. (Leaving aside whether rap is a modern folk music.)

And someone else got offended by the perceived antisemitism in Lord of the Dance. I think in a song, it is unfair to analyse the grammar and syntax too closely, but I always assumed that "they" in that song didn't refer exclusively to the Jews every time it appears, or to any other group of people but to the more nebulous "they", meaning "mankind generally". It's a song, not a legal document.

Me, I'm offended by kids being taught religious songs at school anyway.
